    Thanks for pointing out the cable drive site. Was very interesting reading. I particularly liked the cheesy 80s advertising.

    It seems to me that designing a ‘greasless’ bicycle will do a lot to encourage more bicycle commuting. I always hear people complaining about the dirt.

    I totally dig the compactness of this thing too, especially now that my mixed mode commute is becoming so crowded. It even looks fairly lightweight and looks like something people might try these days.

    I certainly dont want to pour hot water over the idea but here’s what I was thinking :

    1. Its basically like a pulley and cable system, akin to the swing lever drives of that time minus the chain. I certainly have seen more cables breaking before chains. I think you can design around that my playing around with the cross sectional area.He does mention 7×19 cable though but how often will you need to replace them?

    2. Because the pedaling is a linear asynchronized leg motion, there are plenty of accelerations and decelerations at the knee joint instead of a more fluid circular pedaling style. Combined with the thrusting you have to do at the handlebars, there may be more energy lost over time.

    3. As far as power output, this is good for short term cycling but I don’t see the benefits coming in a long 20 mile ride at a good pace.

    Certainly like you all mentioned, its a fun bike to have and tinker around with. Thanks for the post.

    Good morning,
    The other cable drive system of the time that I know about is the Allenax. I did considerable sketching and fantasizing about improving the design and now have an embodiment that would use only chains and eliminate the springs. I’ll see if I can do a sketchup drawing and post it. However, I’m putting more of my time and construction effort into an enclosed drive recumbent which I’ve actually prototyped (roughly). You can see the photos on my website by googling “nick hein hpv”. Go to the “Post Express” picture/link. I’ve since completed the (rideable, single-speed) mockup and started on the prototype. I encourage you to steal/copy/plagiarize this design all you want. I’m not in a position to build it at the moment.

    I knew that someone would bring up the Allenax. That lever driven design was one on the ones that used cables and chains as Ron pointed out. The advantage I see with the cable system is the ability to hide the transmission in the tubing. That is a big reason why I think this idea has more merit as a potential wheelchair or handcycle design. With a hand driven design, cable breakage should be less of an issue, right?

    Nick, thanks for sharing the designs on your site too. Looks like some interesting stuff.

    See the Stepster scooter bike at

    Doesn't seem to be on sale, but the video makes it look like a cable system.

    I am aware of the existence of several of these cable cm1000 bikes. I can be contacted at|
